WHEEL-MOUN TING.

To all whom it may concern Be it known that I, ALFRED H. WORREST,

' of Lancaster, in the county of Lancaster and description of theinvention, such as will enable others skilled in the art to which itappertains to make and use the same.

. This invention relates to improvements in mountings and moreparticularly to means for effecting the mountings of the .axle box of awheel upon the axle spindle,-one ob ject of the invention being toprovide simple and efiicient means whereby the fixed race-way sleeves ofa ball-bearing mounting shall be applied to the spindle in such manneras to effectually prevent them from turning thus eliminating wearbetween said raceway sleeves and the spindle.

A further object is to construct the mounting-in such manner that theinnerraceway sleeves shall be permanently located within the axle boxbut readily removable with the latter from the spindle, and so that thepositions of said inner raceway sleeves relatively to the spindle maybereadily adjusted to compensate for wear of the bearing faces of saidraceways.

With these and other objects in view, the invention consists in certainnovel features of construction and combinations of parts as hereinafterset forth and pointed out in the claims.

Fig. 2 is a sectional view on the line wm of Fig. 1; Fig. 3 is asectional View on the line 3 of Fig. 1, and Fig. 4 is a View in sideelevation of the raceway sleeve 15.

1 represents a portion of an-axle provided with a spindle 2 having ashoulder 3 at its juncture with the axle and with a longitudinal grooveor key seat which may extend from end to end of said spindle. The majorportion of the spindle may be made tapering, but a portion at the innerend thereof near the shoulder 3 is made cylindrical as indicated at 5.The other end of the spindle is contracted somewhat to form an annularshoulder 6 and the free end of the contracted portion of the spindle isthreaded for the reception of a nut 7 as will be more fully hereinafterexplained.

Specification of Letters Patent.

Patented Oct. 5, 1915.

Application filed March 15, 1913. Serial No. 754,616.

An axle box 8 is mounted on the spindle 2 and its rear end is enlargedas shown at 9, the outer end of the axle box being enlarged by means ofa sleeve 10 which is pressed or otherwise secured on the outer end ofthe tubular portion of the axle-box. A sleeve 11 is pressed or otherwisesecured in the enlarged rear portion of the axle-box and this sleeve isprovided interiorly with an annular groove which forms a raceway 12 foran annular series of balls 13. The cooperating raceway 14 for theseballs is formed by means of a groove in the exterior peripheral face ofa sleeve 15 and these raceways 12 and 14 have such depth that the ballswill be almost completely inclosed, thus giving bear ings for the ballsthroughout nearly the whole of their surfaces. By such construction, thebutt raceway sleeve 15 (which is secured to the spindle as presentlyexplained) will be permanently located within the axle box and willberemovable with the latter from the spindle. v

The butt raceway sleeve 15 will (when the parts are assembled on thespindle) be disposed on the cylindrical portion 5 of the spindle fromwhich it may be readily removed without danger of wedging or binding,when the wheel is removed from the spindle. It is important however,that, when in use. the butt raceway sleeve shall be prevented fromturning on the spindle, as otherwise said sleeve and also the spindleitself would be subjected to wear and the sleeve would ultimately becomesufliciently loose to permit rattling. Furthermore, means for lockingthe raceway sleeve to the spindle and for effecting its adjustmentrelatively thereto to compensate for wear of the lower portion of thebearing, should be such as to facilitate the assembling or applicationof the wheel on the spindle. To insure the accomplishment of theseresults, the features of construction now to be explained are employed.

The butt raceway sleeve 15 is provided with any desired number of radialholes 16 and said sleeve is made in its outer face with an annulargroove 17 which intersects these. Pins or keys 18 pass loosely throughthe holes 16, and each is provided with a transverse hole for thepassage of a spring 19. This spring may conveniently be made of a singlepiece of spring wire encircling the sleeve within the groove 17 therein,and serves to press the pins or keys inwardly and permit them to yieldoutwardly. In the sleeve 15 to enter the same. Both 'pins or keys arefree to yield and when the sleeve becomes disposed on the cylindricalportion 5 of the spindle, one ofthe pins or keys will be forced into thegroove or keyway 4 in the spindle automatically, while the remaining keyor keys will be pressed outwardly by engagement with the spindle. Byusing a single spring for all the pins or keys, the key or keys whichare pressed outwardly will place the spring under greater than itsnormal tension and hence the retention of the single key in the grooveor keyway 4 will be insured.'

' As is wellknown, the under portion of the stationary raceway (theraceway of sleeve 15 in the present instance) will wear faster than theupper portion. In order to compensate for such wear, the wheel may beremoved andthen replaced in a manner to cause'a diiferent key to engagethe keyway,thus, in effect turning the sleeve so that a diflerent orless worn portion of the raceway will become disposed at the bottom. Thesleeve 10 which forms the forward portion of the axle box is providedinteriorly with a groove or raceway 20 for the accommodation of balls 21and the cooperating groove or raceway 22 is formed in a raceway sleeve23 held within the sleeve 10 when the axle box is removed from thespindle, by said balls. The raceway sleeve 23 comprises two identicalsections held together' by a tube 24: passin through said sections andupset at its en s.

When the axle box containing the raceway sleeves 15 and 23, is placed onthe spindle, the raceway sleeve will become disposed on the butt end ofthe spindle and locked thereto as hereinbefore explained, and the innerend of the outer raceway sleeve 23 will abut against the shoulder 6nearthe outer end of the spindle. A point nut 7 will then so be screwed onthe threaded end'of the spindleand this nut is-made on its inner facesurrounding the threaded opening therein,

-with an annular enlargement 27 which engages the outer end of theraceway sleeve 23., In this manner, the outer-raceway sleeve" 23 isclamped ti htly between the shoulder 6 and the nut and is thus heldrigidly on the spindle.

As the raceway sleeve 15 is removable with the axle box, it is apparentthat by removing the wheel and then replacing it so that the sleeve 15will be difierently disposed on the spindle, adjustment 0 said sleevefor wear may be efi'ected.

Having fully described-my invention what I claim as new and desire tosecure by Letters Patent, is

1. The combination in a device of the character described, of a spindlehavin a single groove, a removable radial bearing device. encircling theinner end portion of the spindle, a plurality of keys passing freelythrough a wall of the removable bearing device, and a single springengaging said keys and pressing them into engagement with the spindle,one of said keys adapted to enter the groove in the spindle.

'2. The combination in a device of the character described, of a spindlehaving a recess, a removable ring encircling said spindle and having anannular groove in its ALFRED H. WORREST.
